Is there a good way to use FiderisTM single cell test fixture to do materials testing for flow fields?
Yes, there are two options. The first is to request uncoated fixtures made from a material meeting your specifications and then plating or coating the test fixture with the material under test. The second is to use a modified version of the single cell test fixture made specifically for material testing. The modified version includes a 0.010 inch deep recess over the surface of the serpentine flow field that may be fitted with a square of expanded or perforated material being tested. This design allows the majority of the flow field to be provided by the serpentine path while minimizing the amount of material under test. This design also places the material under test in intimate contact with the MEA in both the anode and cathode.
